Product profile：
Urine DNA sample collection is a new method of non-harmful and painless DNA sample collection when compared with routine blood DNA sample collection. The urine DNA sample preservation tube preserves not only the genome in the urine, but also the free circulating DNA (cfDNA) in the urine. Because studies have proved that plasma cfDNA is partly derived from the tumor, fetus and transplanted organs, and that plasma free DNA can be transported into the urine through the kidney, this brings great application value for non-invasive diagnosis. Urine DNA sample storage tube After urine sample collection, the DNA is stably stored at 6-35℃ for up to 7 days. Urine DNA sample preservation tube is composed of EDTA anticoagulant and special protective agents, which can effectively inhibit nucleases in urine and avoid the release of genomic DNA from exfoliated cells in urine, but also can be used to preserve blood cells in urine. It has the advantages of convenient collection, non-invasive, room temperature storage and transportation, which provides great convenience for the transportation and storage of urine samples. This product is suitable for studies where noninvasive prenatal screening is associated with early diagnosis of some diseases.
